How much Compression are the fast nitrous Iorn Block ls1's running....

My motor is currently being machined and pistons are a 13cc dome and 65cc head. I was planning to do a dual stage nitrous setup for a total of 300-400hp

anyone running 15:1 compression or more on that much nitrous?

 

What cam are you running? Piston to valve may be an issue for you with a 13cc dome.

 

Currently the cam is on the big side 26X/26X .660+/640+ but the pistons have been made to accomodate 800 lift and 310 duration....

My question comes directly about the compression with a 300 shot.

 

Bump for curiosity....

 

Whatever compression you want provided you can keep knock in check. That much dome with that huge cam, with the huge shot is gonna be a huge challenge. And 15:1 SCR doest mean **** because I think your DCR will be killed with that huge cam anyway. Good luck keeping it in one piece.

 

Dynamic is 9.12 still plenty high enough if you ask me.....
